Avoid the Innovas unless you're really destitute. They use plain steel studs which don't last as long as the carbide ones. Plus there's a reason why they have an optional stud replacement kit and the others don't. But, in a pinch, they'll get you through a winter.
Have you bought studded tires from BTD? I only ask because the quoted prices are very nice, but I was wondering if there's a reason. I'm looking at the Marathon Winters, and at prices that look to be $40/set cheaper than elsewhere when you consider the below-cost shipping they offer, it's attractive enough to actually make me skeptical.
What's the deal? Are those guys good, or do the tires come missing half the studs?
